Highlights
 Access density and processing capability
RSR20-14 comes with four SIC slots, which supports up to two non-channelized E1、
four ISDN U or S/T interfaces, three sync serial interfaces, three 3G interface cards,
four Layer 2 switching Ethernet interfaces, and 32 asyn serial interfaces to provide the
high-density remote OA solution. Moreover, RSR20-14 comes with one NMX slot that
supports 24 Layer 2 switching Ethernet interfaces. The E1 interface complies with
ITU-T G.703; the ISDN U interface complies with ITU-T G.961 ANSI T1.601, and the
ISDN S/T interface complies with ITU-T I.430. The sync serial port can connect the
networks such as DDN, frame relay, and X.25. These make the router suitable as an
access router for large/medium-sized branches.
 Reliability
Backup center technology greatly improves network reliability, various backup modes
are available for high reliability requirements
 Compatibility
RSR20-14 is fully compatible with equipments of other suppliers
 Power supply
By using high-quality power supplies, RSR20-14 provides protection for surge,
overvoltage, undervoltage, overcurrent and other power problems to deliver stable and
reliable output, and supports transient power interruption protection.
 External Structure
With the standard 19" chassis shielding electromagnetic radiation, RSR20-14 can be
installed on racks. It is highly resistant to shock, high/low temperatures, and
electromagnetic radiation, and works stably.

The NMX switch module, SIC-4ESW and the Eth0/1 on the panel cannot be
used at the same time. They are prioritized in the following order: NMX switch
module > SIC-4ESW > Eth0/1. That is, once the NMX switch module is
inserted, the SIC-4ESW and Eth0/1 cannot be used. When the SIC-4ESW is
inserted without the NMX switch module, the Eth0/1 cannot be used. The
Eth0/1 can be used only when the NMX switch module and SIC-4ESW are
not inserted.
